Wiper motor - does it care?

["James Pickard" <geowiz.sgy@cox.net>]

I'm about ready to put the wiper motor in the bug-eye, but I had a thought
that didn't die of loneliness.  The wiper motor is a two-speed from a later
model Spriget, and it is undoubtedly negative ground.  My bug-eye is
positive ground.  Does the wiper motor care?  Will it work?  If it runs
backwards, does it matter?  The wipers should still go back and forth.
Anybody an authority on this?  I hate learning things the hard way.
